摘要: With a direct force modulation technique we measured the regional stiffness of self-assembled-(SAM) films. A magnetic thin film was deposited at end backside AFM cantilever so as to apply forces directly tip through external field an electric coil. This is able detect difference between phase-separated monolayer films with two similar stiffnesses composed hydrocarbon and fluorocarbon identify components film. We obtained effective spring constant 4.8 N/m on SAM 6.5 applied 1 nN.
